FYI, posted an 8 Jun 12 patch with
a new rerun command. This allows
you to read a series of snapshots from
a dump file (atom or custom style only
for now), and re-process them with LAMMPS,
e.g. to compute other quantities or use
a new potential that wasn't used during
the original run. I.e. a method for doing
post-processing with LAMMPS itself.
